The determination of a "least quantile of squares regression line" for all quantiles
(Elsevier Science, 1994-09-01)
Least median of squares regression has shown to be an extremely useful tool in robust regression analysis. In this note, we extend this concept to least quantile of squares regression, and propose a polynomial algorithm ...

Locating an undesirable facility by generalized cutting planes
(Informs, 1998-08-03)
We address the problem of locating an undesirable facility within a compact set by minimizing a strictly decreasing boundedly lower subdifferentiable function of the squared Euclidean distances to a set of fixed points. ...

Polynomial algorithms for parametric minquantile and maxcovering planar location problems with locational constraints
(Springer, 1998-12-01)
A location is sought within some convex region of the plane for the central site of some public service to a finite number of demand points. The parametric maxcovering problem consists in finding for eachR>0 the point from ...

A characterization of efficient points in constrained location problems with regional demand
(ELSEVIER SCIENCE BV, 1996-02-01)
In this paper we characterize the set of efficient points in the planar point-objective location problem under a convex locational constraint, when distances are measured by a strictly convex norm in ~2 and the set of ...

Undesirable facility location with minimal covering objectives
(ELSEVIER SCIENCE BV, 1999-11-19)
An undesirable facility is to be located within some feasible region of any shape in the plane or on a planar network. Population is supposed to be concentrated at a finite number n of points. Two criteria are taken into ...
